Populations in high rotational states of HF far from rotational- translational equilibrium have been observed in reactive fast flows in a large diameter flow tube. The high rotational states are assumed to be produced from the chemically generated, vibrationally excited HFv, J by direct V yields R intramolecular energy transfer collisions with ground-state H2, HF, or Ar species. In a chemical kinetic analysis it is shown that the results are consistent with the multiquantum V yields R energy-transfer mechanism for HFv, J M proposed by R. L. Wilkins for HFv, J HF and D. L. Thompson for HFv, J Ar. Experimental studies are made by monitoring HF R-R spectral emissions between 9 to 22 micrometer with a sensitive bolometer.
